Possible sources of variation in the working of seed predation includes: (1) grass litter or "mulch" acting as a shelter for seed predators and increasing predation (Reader, 1990; Reed et al., 2006), (2) seed predators preferring some seed species over others (Myster and Pickett, 1993; Myster, 1997; Myster, 2003), (3) predators responding to differences in seed density (Myster and Pickett, 1993), (4) season of the year affecting seed predation (Lindroth and Batzli, 1984) and (5) because much of the research has focused on
tall-grass prairie (Collins and Adams, 1983; Knapp et al., 1998) with few examples in other grassland types (Reed et al., 2006), predation levels differing among prairie-types.

Partly as a result of these classic restoration efforts, it is now clear that
